IMPROVEMENT IN MACHINES FSR COILING HOQPS.

Specification forming part of Letters Patent No. 59,29, dated February2, 1875; application tiled July 17, 1874.

To all whom fit may concern:

Be it known' that I, JAMES ToMLrNsoN, of Goderich, in the county ofHuron and Province of Ontario, Canada, have invented certain new anduseful Improvements in Machines for Goilin g Hoops, of which thefollowin gis a specication:

The object of my invention is to coil barrelhoops into compact rollsafter steaming to render them pliable; and it consists in theconstruction and arrangement of parts, as hereinafter described.

In the drawings, Figure l is a plan of my improved machine Fig. 2, afront elevation, Fig. 3, a vertical section of Fig. l; Fig. 4, adiagram, showing the device for discharging. or throwing oft' thecompleted coil from the forming-wheel.

A represents the frame in which is mounted a shaft, B, carrying theforming-wheel C at one end. The coil is formed on this wheel by windingthereon as the wheel revolves, being placed one on the top of anotherfor the purpose. The hoops have to be previously steamed to wind well. Dis a iiexible metallic strap or band attached at one end to the pivotedarm E, and at the other to a weighted lever, F, as shown most clearly inFig. 2. By this means the main portion of the formingwheel is envelopedby the strap, leaving only an open throat or passage, a., at the top,

through which the splints are fed to be coiled.

The lever F has a longitudinal slot, b, at its rea-r end, through whichpasses the pivot c', and at a suitable position it has a cord or` chain,d, which passes upward over pulleys f f, and has attached to theopposite end a' weight, g. The object of this arrangement is' to allowthe enlargement ot' the strap as the hoops are fed in one over another,as before described. As the coil enlarges the strap is pressed down soas to increase in its distance from the wheel, and this action isallowed by the lever, which depresses and also moves endwise under theaction. At the same time the weight will draw up on the lever, and serveto keep the metallic strap in constant contact with the coil, which isessential to make it close and tight. The pivoted arm E has also animportant action in allowing a free movement of the strap in variouspositions, so as to make it bear at all points on the coil. Theseseveral features for holding and allowing the-winding` of the coil,constitute important parts of my'invention.

In front of the forming-wheel is a face-plate, G, and in the rear acorresponding fixed ring, H, said parts boxing or inclosing the spacearound the circumference of the wheel, to keep the hoops in place one outop of another, as they are coiled.

The face-plate G is made to move out and in, to allow the discharge ofthe finished coils, as follows: On the rear of the frame A rests across-bar, I, which slides back and forth freely. Rods h h connect thiscross-bar with the lugs t' c' of the face-plate, said rods havingsuitable bearings in the frame, to insure their running properly. Spiralsprings 7c 7c are placed upon the rods, or some equivalent arrangementis employed, whereby the faceplate is drawn back, as before described,to rest close to the forming-wheel. In the frame is mounted across-shaft, K, upon which", at opposite ends, are mountedpulleys LL,cords or chains l l, winding on the pulleys LL, connect with cross-barI, and `one of these cords, after passing around its pulley, extendsdown and is attached to a foot-treadle, M. By operating this treadle itwill be seen that the cross-bar I, and consequently the face-plate G,will be thrown out. The bar I is provided with two projecting rods, NN,- whose distance apart is a little greater than the diameter of theforming-wheel so that when thrown forward by the movement of the bar,before described, they will strike the sides of the coil each side ofthe wheel, and thus throw it olf from the wheel, to allow the forming ofa new coil. Thus it will be seen the movement of the face-plate awayfrom the forming-wheel, and the forcing of the nished coil from itsplace, are simultaneous. From the formingwheel the coil drops into aninclined trough, P, and rolls oft' out of the way. The action of therods N is most clearly illustrated in Fig. 4.

On the back side of the forming-wheel is pivoted a clamp, Q, as shown inFig. 3. One end, m, is made to extend over the face ofthe isms@ wheel,While the other, n, passes through a slot made in the wheel, andprojects in front so as to come in contact with the face-plate, whichpresses back against it, as shown at n. The object of this arrangementis to clamp and hold the first end of the first hoop in starting thecoil. This end is inserted under the hook m, when the back action of thefaces plate will cause it to be clamped down upon the face of the Wheel.The next hoop is then applied under the end of that one Wou nd, andWound up till the Whole coil is complete.

To the face-plate is pivoted an arm, R, Figs.

' lwand 2, Which Vhas a pin, p, that lies over the face of theforming-Wheel in the throat a. A oord or chain, q, connects the end ot'this arm with a foot-treadle, S, beloW.

When the coil has been fully Wound the Wheel is turned to bring the lastend of the last hoop under pin lo, which is then clamped down upon it bypressing ou treadle S. rlhis is for the purpose of holding the end ofthe hoop While a nail is driven through the same for binding to thecoil.

The object of thus coiling hoopsis to get them in compact form fortransportation and storage, and also to bind them into the approximate'orm for use on barrels, which curved form they always retain afterbeing once steamed and bent.

l. In a machine for coiling hoops, the combination of a forming-Wheel,C, encircling band or strap D, pivoted arm E, and the Weighted le- VerF, arranged and operating substantially as set forth.

2. In a machine for coiling hoops, the movable faoe-plate G, pivotedclamp Q, lever R, and pin 19, in combination with the forming- Wheel C,encircling band or strap D, pivoted slotted arm E, and weighted lever F,all arranged and operating substantially as de scribed.
